One new flavonol glycoside, kaempferol 3-(4 ",6 "-diacetylglucoside)-7-rhamnoside and three other known kaempferol glycosides: kaempferol 3-glucoside-7-rhamnoside, kaempferol 3-(6 "-acetylglucoside)-7-rhamnoside, and kaempferol 7-rhamnoside, were isolated and characterised from flowers of Delphinium formosum. The structures were elucidated by spectral and chemical methods.
